Description

Technical Field

[0001] This utility model relates to a hinge, and more particularly to a hinge that can be applied to electronic devices such as laptops. Background Technology

[0002] Users often need to use cooling stands to elevate the back of their laptops when using electronic devices such as laptops, in order to increase the laptop's cooling space and improve keyboard comfort. However, these stand-ups are not very convenient to store or use, and their stability during use could be improved. Therefore, finding a convenient and stable way to elevate the back of a laptop while using it is an important issue. Utility Model Content

[0003] One object of this invention is to provide a shaft that can improve at least one problem in the prior art.

[0004] In some embodiments, the rotating shaft of this utility model includes a base, a rotating unit, and a rotating foot pad. The rotating unit includes a rotating member and a connecting protrusion. The rotating member is disposed on the base and can rotate relative to the base about a first rotation axis parallel to the lateral direction between a first position and a second position. The connecting protrusion is linked to the rotating member and can rotate relative to the base about a second rotation axis parallel to the lateral direction. The rotating foot pad is pivotally mounted on the base and can rotate relative to the base about a third rotation axis parallel to the lateral direction between a folded position and an upright position. The rotating foot pad has a recessed rail formed at one end along the lateral direction, a foot pad body at the other end, and a pivot portion located between the recessed rail and the foot pad body and pivotally connected to the base. The connecting protrusion of the rotating unit is slidably disposed within the recessed rail. When the rotating component is in the first position, the rotating foot pad is in the retracted position, and the foot pad body of the rotating foot pad is relatively close to the base; when the rotating component rotates to the second position, the rotating foot pad is driven to rotate to the upright position through the connecting protrusion, and the foot pad body of the rotating foot pad is relatively away from the base.

[0005] In some embodiments, the rotating member passes through a transition position during its rotation relative to the base between the first and second positions. The concave rail has a connected drive rail portion and an arc-shaped rail portion. When the rotating member is in the first position, the connecting protrusion is located at the junction of the drive rail portion and the arc-shaped rail portion, and the rotating foot pad is located in the retracted position. When the rotating member rotates from the first position to the transition position, the connecting protrusion slides towards the drive rail portion and returns to the junction of the drive rail portion and the arc-shaped rail portion, driving the rotating foot pad to rotate to the supported position. When the rotating member rotates from the transition position to the second position, the connecting protrusion slides along the arc-shaped rail portion, and the rotating foot pad does not rotate.

[0006] In some embodiments, the drive rail is straight and tangent to the arc-shaped rail.

[0007] In some embodiments, the rotating unit further includes a cam member that is linked to the rotating member and can rotate relative to the base about the second rotation axis, the cam member having the connecting protrusion located at the protrusion.

[0008] In some embodiments, the rotating unit further includes a drive gear sleeved on the rotating member and rotating synchronously with the rotating member, the drive gear meshing with the cam member.

[0009] In some embodiments, the rotating foot pad has a first foot pad portion relatively close to the pivot portion and a second foot pad portion relatively far from the pivot portion; when the rotating foot pad is in the folded position, the first foot pad portion is lower than the second foot pad portion; when the rotating foot pad is in the upright position, the second foot pad portion is lower than the first foot pad portion.

[0010] The beneficial effect of this utility model is that the rotating foot pad in the hinge can be linked with the rotating component through the cooperation between the connecting protrusion and the concave rail. When the rotating component rotates from the first position to the second position, the rotating foot pad can be linked to rotate from the retracted position downwards to the supported position. Therefore, when the hinge is used in electronic devices such as laptops, the rotating foot pad can be used to conveniently elevate the back of the laptop when using it. Attached Figure Description

[0022] See Figures 1 to 3 This utility model discloses an embodiment of the hinge 100, applicable to an electronic device 200, exemplified as a laptop computer, but not limited thereto. The electronic device 200 has a first housing 201 and a second housing (not shown). The first housing 201 may, for example, include a keyboard, screen, and touch area (not shown). The hinge 100 connects the first housing 201 and the second housing, allowing the second housing to open and close relative to the first housing 201. The hinge 100 includes a base 1, a rotating unit 2, and a rotating foot pad 3.

[0023] See Figures 1 to 4The base 1 is suitable for being disposed on the first housing 201. In this embodiment, the base 1 has a mounting plate 11 extending in a left-right direction D1 (lateral direction) and a front-back direction D2 and for being disposed on the first housing 201, an assembly plate 12 extending in the front-back direction D2 and a vertical direction D3, and a connecting plate 13 connecting the mounting plate and the assembly plate.

[0024] See Figures 1 to 5 The rotating unit 2 includes a rotating component 21, a cam fixing component 22, a drive gear 23, and a cam component 24. The rotating component 21 is disposed on the assembly plate 12 of the base 1 and can rotate relative to the base 1 around a first rotation axis A1 parallel to the left-right direction D1 between a first position and a second position. The rotating component 21 also passes through a transition position during its rotation between the first and second positions. The cam fixing component 22 has a fixing plate 221 that is sleeved on the rotating component 21 without rotating synchronously with it, and a fixing shaft 222 extending from the fixing plate 221 along the left-right direction D1 and inserted into the assembly plate 12 of the base 1. The drive gear 23 is sleeved on the rotating component 21 and rotates synchronously with it. The drive gear 23 is specifically located between the assembly plate 12 of the base 1 and the fixing plate 221 of the cam fixing component 22, and has a first tooth 231.

[0025] The cam member 24 is located between the assembly plate 12 of the base 1 and the fixing plate 221 of the cam fixing member 22. The cam member 24 has a connecting protrusion 241 located at the protrusion and a second tooth 242 that meshes with the first tooth 231. The cam member 24 is sleeved on the fixed shaft 222 and can rotate relative to the base 1 about a second rotation axis A2 parallel to the left-right direction D1. Through the transmission of the driving gear 23, the connecting protrusion 241 (and the entire cam member 24) is linked with the rotating member 21 and can rotate about the second rotation axis A2, and the rotation directions of the connecting protrusion 241 (the entire cam member 24) and the rotating member 21 are opposite to each other. It should be noted that in other embodiments, the connecting protrusion 241 may also be directly formed on the rotating member 21. In such embodiments, the second rotation axis A2 and the first rotation axis A1 coincide with each other, and the rotation axis and rotation direction of the connecting protrusion 241 and the rotating member 21 are consistent with each other.

[0026] The rotating foot pad 3 is pivotally mounted on the base 1 and can rotate relative to the base 1 about a third rotation axis A3 parallel to the left-right direction D1 between a retracted position and an upright position. Specifically, the drive gear 23 and the cam 24 are located on one side of the assembly plate 12 of the base 1 in the left-right direction D1, while the rotating foot pad 3 is located on the other side of the assembly plate 12 of the base 1 in the left-right direction D1. The rotating foot pad 3 has a recessed rail 31 at one end and recessed along the left-right direction D1, a foot pad 32 at the other end, and a pivot portion 33 located between the recessed rail 31 and the foot pad 32 and pivotally connected to the base 1. The recessed rail 31 has a connected drive rail portion 311 and an arc-shaped rail portion 312, the radius of curvature of the arc-shaped rail portion 312 being equal to the distance between the connecting protrusion 241 and the second rotation axis A2. In this embodiment, the drive rail 311 is straight and tangent to the arc-shaped rail 312. However, in other embodiments, the drive rail 311 may be adjusted to be straight as needed, and is not limited to this embodiment. The connecting protrusion 241 of the rotating unit 2 is slidably disposed within the concave rail 31. The assembly plate 12 located between the cam member 24 and the rotating foot pad member 3 has an arc-shaped clearance groove 121 formed through the left-right direction D1 to avoid the connecting protrusion 241. The foot pad body 32 of the rotating foot pad member 3 has a first foot pad portion 321 relatively close to the pivot portion 33 and a second foot pad portion 322 relatively far away from the pivot portion 33.

[0027] In addition, in this embodiment, a torsional friction element 4 can be added to the rotating member 21 to rotate synchronously with the rotating member 21. The torsional friction element 4 is used to generate a frictional force between itself and the cam fixing member 22 to resist the rotation of the rotating member 21, thereby enabling the electronic device 200 to be positioned at various opening and closing angles and improving the user's operating feel when opening and closing the electronic device 200.

[0028] See Figure 1 When the rotating member 21 is in the first position, the second housing is closed relative to the first housing 201. At this time, the connecting protrusion 241 is located at the junction of the drive rail portion 311 and the arc-shaped rail portion 312, and the rotating foot pad 3 is in the retracted position. In this state, the foot pad body 32 of the rotating foot pad 3 is relatively close to the base 1, and the position of the first foot pad portion 321 is lower than that of the second foot pad portion 322.

[0029] See Figure 6When the rotating member 21 rotates from the first position to the transition position, and the second housing opens about 45 degrees relative to the first housing 201, the connecting protrusion 241 slides toward the drive rail 311 to the end of the drive rail 311, thereby driving the rotating foot pad 3 to rotate toward the support position.

[0030] See Figure 7 When the rotating member 21 continues to rotate to the transition position, the second housing opens approximately 90 degrees relative to the first housing 201. At this time, the connecting protrusion 241 returns to the junction of the drive rail 311 and the arc-shaped rail 312, driving the rotating foot pad 3 to rotate to the supported position via the connecting protrusion 241. In this state, the foot pad body 32 of the rotating foot pad 3 is relatively far away from the base 1, and the position of the second foot pad 322 is lower than that of the first foot pad 321. It is worth mentioning that the second foot pad 322 (for supporting the tabletop) of the foot pad body 32 of the rotating foot pad 3 is approximately located below the pivot part 33 of the rotating foot pad 3. Therefore, the reaction force on the foot pad body 32 of the rotating foot pad 3 is unlikely to generate a torque that forces the rotating foot pad 3 to rotate relative to the base 1, thus preventing the rotating foot pad 3 from rotating back to the folded position.

[0031] See Figure 8 When the rotating member 21 rotates from the transition position to the second position, the second housing opens approximately 180 degrees relative to the first housing 201, and the connecting protrusion 241 slides along the arc-shaped rail 312 to its end. The rotating foot pad 3 does not rotate. It should be noted that since the distance between the connecting protrusion 241 on the cam member 24 and the second rotation axis A2 is fixed and equal to the radius of curvature of the arc-shaped rail 312, when the connecting protrusion 241 is located on the arc-shaped rail 312, the rotating foot pad 3 is restricted to the upright position and cannot rotate, thereby preventing the rotating foot pad 3 from rotating back to the retracted position.

[0032] See Figures 9 to 10In a variation of the rotating shaft 100 of this utility model, the difference lies in that the drive gear 23, the cam member 24, and the rotating foot pad 3 are located on the same side of the assembly plate 12 of the base 1 in the left-right direction D1. Additionally, in this variation, a torsion friction plate 5 can be added to the rotating member 21, rotating synchronously with it. The torsion friction plate 5 is located between the fixing plate 221 of the cam fixing member 22 and the assembly plate 12 of the base 1, and is used to generate frictional force against the rotation of the rotating member 21 between the cam fixing member 22 and the base 1. This allows the electronic device 200 to be positioned at various opening and closing angles and improves the user's operating feel when opening and closing the electronic device 200.

[0033] In summary, the rotating foot 3 in the hinge 100 of this invention can be linked with the rotating member 21 through the cooperation between the connecting protrusion 241 and the concave rail 31. When the rotating member 21 rotates from the first position to the second position, the rotating foot 3 can be linked to rotate from the folded position downwards to the upright position. Therefore, when the hinge 100 is applied to electronic devices 200 such as laptops, the rotating foot 3 can be used to conveniently elevate the back of the laptop when using it. Furthermore, through the design of the drive rail 311 and the arc-shaped rail 312 of the concave rail 31, when the connecting protrusion 241 is located at the arc-shaped rail 312, the rotating foot 3 is restricted to the upright position and cannot rotate, thereby preventing the rotating foot 3 from rotating back to the folded position.

Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model shall still fall within the scope of the present utility model.
